客运专线主要技术标准选择分析

Selection analysis on main technical standards of passenger dedicated line

以杭南长客运专线为例,在遵循高速铁路主要技术标准选择原则的基础上,对最小曲线半径、最大坡度和到发线有效长度三个工程标准进行了计算和比较。研究结果表明:杭南长客运专线的最小曲线半径一般情况下取7 000 m,困难条件下取5 500 m;客运专线的到发线有效长度取650 m。

Based on the selection principles of the main technical standards for high-speed railway, the Hangzhou-Changsha passenger dedicated line as the research target. The three engineering standards such as minimum curve radius, maximum grade and arrival-departure track effective length were calculated and compared. Research shows that ： the minimum curve radius of Hangzhou-Changsha passenger dedicated line were rec-ommended as 7 000 m in general case and 5 500 m in difficult conditions, arrival-departure track effective length of passenger line taken as 650 m.
